$$\frac{i \sin{\left(p \right)} \left(2 x - 5\right)}{2} = \frac{\left(-1\right) \sqrt{2}}{2}$$
Solución detallada
Tenemos la ecuación
$$\frac{i \sin{\left(p \right)} \left(2 x - 5\right)}{2} = \frac{\left(-1\right) \sqrt{2}}{2}$$
cambiamos
$$\frac{i \left(2 x - 5\right) \sin{\left(p \right)}}{2} - 1 + \frac{\sqrt{2}}{2} = 0$$
$$\frac{i \sin{\left(p \right)} \left(2 x - 5\right)}{2} - 1 - \frac{\left(-1\right) \sqrt{2}}{2} = 0$$
Sustituimos
$$w = \sin{\left(p \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
Sumamos los términos semejantes en el miembro izquierdo de la ecuación:
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$\frac{i w \left(2 x - 5\right)}{2} + \frac{\sqrt{2}}{2} = 1$$
Dividamos ambos miembros de la ecuación en (sqrt(2)/2 + i*w*(-5 + 2*x)/2)/w
Obtenemos la respuesta: w = i*(-2 + sqrt(2))/(-5 + 2*x)
hacemos cambio inverso
$$\sin{\left(p \right)} = w$$
sustituimos w:
$$\frac{i \sin{\left(p \right)} \left(2 x - 5\right)}{2} = \frac{\left(-1\right) \sqrt{2}}{2}$$
cambiamos
$$\frac{i \left(2 x - 5\right) \sin{\left(p \right)}}{2} - 1 + \frac{\sqrt{2}}{2} = 0$$
$$\frac{i \sin{\left(p \right)} \left(2 x - 5\right)}{2} - 1 - \frac{\left(-1\right) \sqrt{2}}{2} = 0$$
Sustituimos
$$w = \sin{\left(p \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
-1 - -sqrt+2)/2 + i*w2*x/2+5/2 = 0
Sumamos los términos semejantes en el miembro izquierdo de la ecuación:
-1 + sqrt(2)/2 + i*w*(-5 + 2*x)/2 = 0
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$\frac{i w \left(2 x - 5\right)}{2} + \frac{\sqrt{2}}{2} = 1$$
Dividamos ambos miembros de la ecuación en (sqrt(2)/2 + i*w*(-5 + 2*x)/2)/w
w = 1 / ((sqrt(2)/2 + i*w*(-5 + 2*x)/2)/w)
Obtenemos la respuesta: w = i*(-2 + sqrt(2))/(-5 + 2*x)
hacemos cambio inverso
$$\sin{\left(p \right)} = w$$
sustituimos w:
